There was also an ICM poll of marginals. It showed support in these seats at CON 35%(-1), LAB 35%(-2), LDEM 22%(+3) – so only a minor Lib Dem boost in these seats. These levels of support equate to a swing to the Conservatives of 6.8%, so just the swing they would need for an overall majority

Anthony King, who does know more than most about these small matters, had this to say earlier in the day:

If the Tories could somehow edge upwards from their present 33 per cent to 37 per cent, and if support for both the Lib Dems and especially Labour fell back, Mr Cameron could still win an overall majority - but his majority would be tiny.
